[0032] Examples of the present invention are figure 1 As shown, wherein the pumping light is the first Q-switched quasi-CW Nd:YAG laser 1, the second Q-switched quasi-CW Nd:YAG laser 2, and the third Q-switched quasi-CW Nd:YAG laser 23, all of which have a pulse width of 50ns, A laser with a repetition rate of 30KHz, a wavelength of 1064nm, a peak power of 8.6KW, and an output pump power of 5.2W. L1 is 138mm and L2 is 165mm. The thickness ratio of the four crystals of the birefringence interference filter 8 is 1:2:4:9. The angle of incidence for the first prism pair 10 is 40 o , The distance between the vertices of the two prisms is 57cm, and they are placed in parallel with a slight angle of 8 o , tap the concave spherical mirror 5, wherein the self-mode-locked correlation, and slightly adjust the placement angle of the birefringent interference filter 9 .
[0033] The wavelength of the laser output through the coupling output mirror is 1510nm, the output power here is 44...
